The "N" series tractors are some old workhorses. Once you get one running right, you can't hardly hurt it. They're about as basic as the internal combustion engine can get, and parts are available for them everywhere and very cheap. One little 100 +/- page service manual (F-04) covers repairs on every part of the tractor.
I just inherited a '52 8N from my father. It smoked like a freight train. Would actually run out of oil before gas. I tore it down in the garage, ordered the parts online and rebuilt the engine myself. Found some rod bearings dated '79 in it, so it had been 30 years since the last rebuild. I did an in-frame overhaul, at a cost of around $500. That included getting a new carb for it too. Now she runs like a top, and works like two pissed off mules. Still using the old 6 volt generator system, and points. Starts in less than two full revolutions. And I know the points in there now are over 3yrs old because I changed them for my dad last time it was done.
The N's are some great old pieces of history. I bet Henry never thought so many of them would still be in regular use 60yrs later.
I've driven newer tractors, and you bet they're nice. Hydrastatic drive, cruise control, power steering, 4wd, nice cushy seats, etc. But you definitely pay for those features. I figure another rebuild for the old ford when I'm 65-70 years old and it'll all be money well spent.
The N's down here can be gotten for around $2500 (nicer specimens). But they're everywhere down here. Not sure about your neck of the woods.
